A Worm Model Based on Artificial Life for Automatic Segmentation of Medical Image

We constructed an intelligent deformable model called worm model.The model has a central nervous system,vision,perception and motor systems.It is able to memorize,recognize objects and control the motion of its body.The new model overcomes the defects of existing methods since it is able to intelligently process the image segmentation using more pieces of information available rather than using merely pixels and gradients.The experimental results of segmentation of the corpus callosum from MRI brain images showed that the proposed worm model is able to segment medical images automatically and accurately. For those images that are more complex or with fragmentary boundaries,the superiority of the worm model is particularly evident.
